To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Objective To investigate the impact of graft type on perioperative outcomes and long-term prognosis in patients undergoing surgical repair of post-myocardial infarction ventricular septal rupture (VSR) with concurrent coronary artery bypass grafting (CABG). Methods A retrospective analysis was conducted on clinical data from patients who underwent VSR repair and concurrent CABG at Fuwai Hospital between 2005 and 2022. Patients were divided into an arterial graft group and a saphenous vein graft (SVG)-only group based on the type of bypass grafts used. Clinical outcomes were compared between the two groups. Results A total of 92 patients were included, comprising 56 males and 36 females, with a mean age of (62.4±7.9) years. The arterial graft group consisted of 60 patients, and the SVG-only group consisted of 32 patients. There were no statistical differences between the two groups in age, gender, body mass index, past medical history, time interval from myocardial infarction to surgery, or culprit vessel distribution (P>0.05). A higher proportion of patients in the SVG-only group received preoperative intra-aortic balloon pump (IABP) support (56.3% vs. 35.0%, P=0.049). However, cardiopulmonary bypass time, aortic cross-clamp time, and early mortality rates were similar between the two groups (P>0.05). Follow-up data revealed no statistically significant differences in cumulative 10-year survival (82.8% vs. 80.0%, P=0.940) or freedom from major adverse cardiovascular and cerebrovascular events (49.6% vs. 58.6%, P=0.491) between the SVG-only and arterial graft groups. Furthermore, graft type did not significantly affect long-term mortality in patients with a culprit vessel in the left anterior descending artery or those with multivessel disease. Conclusion In patients undergoing delayed repair of VSR with concomitant CABG, the use of arterial or saphenous vein grafts does not significantly impact perioperative outcomes or long-term prognosis. Future research should further explore the benefits of different revascularization strategies to optimize treatment for this population.

BackgroundPersistent cognitive impairment is prevalent among patients with stable schizophrenia. While serum total bile acid （TBA） level in acute-phase patients are known to be associated with cognitive dysfunction， the relationship between serum TBA and multi-dimensional cognitive functions in stable phase patients remains unclear. ObjectiveTo investigate the correlation between serum TBA level and cognitive function in patients with stable schizophrenia， and to evaluate its predictive value for cognitive impairment， thereby providing a serological biomarker for the timely identification and objective assessment of cognitive dysfunction. MethodsA cross-sectional study was conducted on 137 inpatients with stable schizophrenia at The Fourth People's Hospital of Yancheng from March to December 2024. All participants met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）. Cognitive function was evaluated using the Chinese Brief Cognitive Test （C-BCT）， patients were categorized into four groups： normal cognition （n=28）， mild impairment （n=28）， moderate impairment （n=47）， and severe impairment （n=34）. Fasting venous blood samples were collected， and serum TBA level was quantified using an enzymatic cycle assay. Spearman correlation analysis was ultilized to determine the relationship between serum TBA level， overall cognitive function， and specific cognitive domains. Binary Logistic regression model was used （adjusting for covariates such as age， gender， and disease duration） to analyze the impact of serum TBA level on overall and individual cognitive functions. The predictive value of serum TBA level for overall cognitive impairment was evaluated using receiver operating characteristic （ROC） curve. ResultsSerum TBA levels differed significantly among the four groups （H=18.677， P<0.01）. Specifically， serum TBA levels in both the moderate and severe cognitive impairment groups were significantly higher than those in the normal cognitive group （adjusted P<0.01）. Serum TBA level was positively correlated with the severity grading of overall cognitive impairment （r_s=0.354， P<0.05）， and negatively correlated with T-scores on the trail making test （r_s=-0.328， P<0.05）， continuous performance test （r_s=-0.247， P<0.05）， digit span （r_s=-0.265， P<0.05）， and symbol coding （r_s=-0.221， P<0.05）. Binary Logistic regression analysis identified serum TBA level as an independent risk factor for overall cognitive impairment （OR=1.322， 95% CI： 1.021 - 1.713， P=0.034）， with a particularly robust predictive ability for impaired information processing speed （OR=1.325， 95% CI： 1.057 - 1.661， P=0.015）. The area under ROC curve （AUC） for serum TBA level in predicting overall cognitive impairment was 0.738， with a sensitivity of 60.61% and a specificity of 78.64%. ConclusionIn patients with stable schizophrenia， elevated serum TBA levels are associated with worse overall cognitive function， as well as deficits in information processing speed， attention， working memory， and executive function. Serum TBA serves as an independent risk factor and exhibits moderate predictive value for overall cognitive impairmen，particularly in the domain of information processing speed. ［Funded by Yancheng Municipal Health Commission Medical Research Project （number， YK2024141）］

Background Bufei Huoxue Capsule (BHC) has gradually been used in clinical practice to treat patients with pneumoconiosis in recent years. However, the comprehensive evaluation of its efficacy and safety is lacking. Objective To systematically assess the therapeutic potential of BHC for pneumoconiosis. Methods By searching 9 databases, e.g. China National Knowledge Infrastructure, Wanfang Database, VIP Chinese Science and Technology Journals Database, SinoMed, Yiigle, PubMed, Embase, Cochrane Library, and Web of Science, randomized controlled trials (RCTs) related to the use of BHC for the treatment of pneumoconiosis were identified. The search covered the period from the inception of these databases to August 31, 2025. This systematic review conformed to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2020. The included studies underwent quality appraisal by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). Subgroup analysis and sensitivity analysis were applied to assess the robustness of results and explore the potential heterogeneity among the studies. Results A total of 19 RCTs were included and all were reported in Chinese. The therapy containing BHC showed a superior impact on forced expiratory volume in one second (FEV₁) (95%CI: 0.38, 0.66; I²=69%, P<0.05), FEV₁% (95%CI: 3.37, 5.72; I²=12%, P<0.05), forced vital capacity (FVC) (95%CI: 0.34, 0.45; I²=0%, P<0.05), FEV₁/FVC% (95%CI: 6.29, 10.35; I²=21%, P<0.05), 6-minute walking distance (6MWD) score (95%CI: 16.32, 27.64; I²=22%, P<0.05), St. George's Respiratory Questionnaire (SGRQ) score (95%CI: −1.47, −1.05; I²=13%, P<0.05), and total effective rate (95%CI: 2.71, 6.78; I²=0%, P<0.05) in patients with pneumoconiosis. In addition, BHC had less adverse reactions reported (95%CI: 0.69, 1.74; I²=0%, P=0.70). Conclusions Combined BHC therapy can significantly improve the lung function and the quality of life in patients with pneumoconiosis, with a good safety profile. However, high-quality RCTs with multicenter, large-sample, double-blind, and standardized protocols still need to be conducted in the future to provide more reliable evidence.

Purpose: Erectile dysfunction (ED) is a common male sexual dysfunction. Gut microbiota plays an important role in various diseases. To investigate the effects and mechanisms of intestinal flora dysregulation induced by high-fat diet (HFD) on erectile function. Materials and Methods: Male Sprague–Dawley rats aged 8 weeks were randomly divided into the normal diet (ND) and HFD groups. After 24 weeks, a measurement of erectile function was performed. We performed 16S rRNA sequencing of stool samples. Then, we established fecal microbiota transplantation (FMT) rat models by transplanting fecal microbiota from rats of ND group and HFD group to two new groups of rats respectively. After 24 weeks, erectile function of the rats was evaluated and 16S rRNA sequencing was performed, and serum samples were collected for the untargeted metabolomics detection. Results: The erectile function of rats and the species diversity of intestinal microbiota in the HFD group was significantly lower, and the characteristics of the intestinal microbiota community structure were also significantly different between the two groups. The erectile function of rats in the HFD-FMT group was significantly lower than that of rats in the ND-FMT group. The characteristics of the intestinal microbiota community structure were significantly different. In the HFD-FMT group, 27 metabolites were significantly different and they were mainly involved in the several inflammation-related pathways. Conclusions Intestinal microbiota disorders induced by HFD can damage the intestinal barrier of rats, change the serum metabolic profile, induce low-grade inflammation and apoptosis in the corpus cavernosum of the penis, and lead to ED.

Background: s/Aims: Sarcomatoid hepatocellular carcinoma (HCC) is a rare histological subtype of HCC characterized by extremely poor prognosis; however, its molecular characterization has not been elucidated. Methods: In this study, we conducted an integrated multiomics study of whole-exome sequencing, RNA-seq, spatial transcriptome, and immunohistochemical analyses of 28 paired sarcomatoid tumor components and conventional HCC components from 10 patients with sarcomatoid HCC, in order to identify frequently altered genes, infer the tumor subclonal architectures, track the genomic evolution, and delineate the transcriptional characteristics of sarcomatoid HCCs. Results: Our results showed that the sarcomatoid HCCs had poor prognosis. The sarcomatoid tumor components and the conventional HCC components were derived from common ancestors, mostly accessing similar mutational processes. Clonal phylogenies demonstrated branched tumor evolution during sarcomatoid HCC development and progression. TP53 mutation commonly occurred at tumor initiation, whereas ARID2 mutation often occurred later. Transcriptome analyses revealed the epithelial–mesenchymal transition (EMT) and hypoxic phenotype in sarcomatoid tumor components, which were confirmed by immunohistochemical staining. Moreover, we identified ARID2 mutations in 70% (7/10) of patients with sarcomatoid HCC but only 1–5% of patients with non-sarcomatoid HCC. Biofunctional investigations revealed that inactivating mutation of ARID2 contributes to HCC growth and metastasis and induces EMT in a hypoxic microenvironment. Conclusions We offer a comprehensive description of the molecular basis for sarcomatoid HCC, and identify genomic alteration (ARID2 mutation) together with the tumor microenvironment (hypoxic microenvironment), that may contribute to the formation of the sarcomatoid tumor component through EMT, leading to sarcomatoid HCC development and progression.

Objective:Accurately grasping the disability levels and characteristics of the elderly population in China is of significant importance for responding effectively to the care service needs of this demographic.Methods:Based on multi-wave data(2011-2023)from three nationally representative aging-related surveys CLHLS,CHARLS and CALSS,this study assessed,compared,and predicted the disability levels and characteristics of China's elderly population.Results:Direct estimates from existing survey data showed low reliability.Integrated multi-source projections indicate that the disability rate among China's population aged 65 and older will follow a phased upward trend,ranging approximately between 12.27%and 15.05%from 2025 to 2050,with the disabled elderly population growing continuously from 25.9 million to 58.64 million.Bathing,toileting,and dressing were the three activities with the highest disability rates.Discussion and Suggestions:Future efforts should focus on improving the construction of an elderly capacity assessment system and addressing the shortage of high-quality disability data.Research should emphasize the evaluation process of item-specific disability among older adults.It is essential to grasp the phased characteristics of changes in disability levels and identify critical windows of opportunity for response.Based on the item-specific disability characteristics of older adults,the focus of elderly care services,facilities,and product supply should be accurately targeted.

Objective To investigate the protective effects and mechanism of Shuilian Fengkui Formula(SFF)of Yao medicine on sequelae pelvic inflammatory disease(SPID)in rats.Methods The SPID rat model was established by mechanical injury coupled with bacterial infection,and then the rats were randomly divided into:the SPID group,the positive drug(Fukeqianjin tablets)group,SFF groups at low,medium and high doses,and the sham-operation group,with 8 rats in each group;SPID group,SFF groups,TLR4 agonist CRX-527(CRX-527)group,SFF plus CRX-527 group,with 8 rats in each group.Corresponding drug intervention was given for 21 consecutive days.The indexes of uterus,spleen,thymus and other organs were calculated.The histopathological changes in rat uterus were observed by HE staining.The levels of interleukin-1β(IL-1β),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),immunoglobulin G(IgG),immunoglobulin M(IgM)in serum were detected by ELISA;The protein expression levels of Toll receptor 4(TLR4),myeloid differentiation factor(MyD88),nuclear factor kappa B p65(NF-κB p65),and phosphorylated nuclear factor kappa B p65(p-NF-κB p65)in rat uterine tissues were detected by Western blot.Results Compared with the sham operation group,the uterine index of SPID group significantly increased(P<0.01),the spleen index and thymus index significantly decreased(P<0.01),the pathological damage of uterine tissue was serious,the contents of IL-1β,IL-6,TNF-α in serum significantly increased(P<0.01),the contents of IgG and IgM significantly decreased(P<0.01),the TLR4,MyD88 protein and the ratio of p-NF-κB p65/NF-κB p65 protein in uterine tissue significantly increased(P<0.01).Compared with the SPID group,the uterine index of the positive drug group and the SFF groups significantly decreased(P<0.05),the spleen index and thymus index significantly increased(P<0.05),the pathological damage of uterine tissue significantly improved,the contents of IL-1β,IL-6 and TNF-α in serum were significantly lowered(P<0.05),the contents of IgG and IgM significantly increased(P<0.05),and the TLR4,MyD88 protein and the ratio of p-NF-κB p65/NF-κB p65 protein in uterine tissue significantly downregulated(P<0.01).However,CRX-527 significantly reversed the effects of SFF on SPID in rats.Conclusion SFF could improve SPID in rats by impeding the inflammatory response,and its mechanism might be attributed to inhibition of TLR4/MyD88/NF-κB signaling pathway.

Objective To construct a classification model for the Los Angeles grading of endoscopic reflux esophagitis based on the SimCLR algorithm's semi-supervised learning framework.Methods The designed learning framework was pre-trained on a large unlabeled dataset through self-supervised learning,and further finely tuned on a small labeled dataset according to the Los Angeles grading criteria.The performance test on the model was conducted on an independent dataset,and the proposed model was compared with the models of supervised learning algorithms and endoscopists in terms of accuracy,Matthews correlation coefficient,and Cohen's kappa value.Finally,Grad-CAM and t-SNE were used for the visualization of the model's interpretation.Results The SimCLR model with ResNet as the backbone network showed superior performance in accuracy(0.840),Matthews correlation coefficient(0.800),and Cohen's kappa value(0.960)than the traditional supervised learning model with ResNet as the backbone(0.680,0.601,and 0.870)as well as junior endoscopists(0.770,0.713,and 0.940),but there was still a slight gap compared with senior endoscopists(0.850,0.813,and 0.960).In addition,the results of t-SNE showed that self-supervised learning in SimCLR was more effective in clustering multi-dimensional samples than traditional supervised transfer learning.Conclusion Compared with traditional supervised learning methods,semi-supervised learning demonstrates outstanding performance even with only a small number of labeled endoscopic images.

Objective To investigate the effects of different administration times on the efficacy and safety of subcutaneous immunotherapy using dual mite extracts in patients with allergic rhinitis(AR).Methods This study was designed as a retrospective cohort analysis.Thirty-nine mite-sensitized AR patients who completed three years of standardized dual-mite subcutaneous immunotherapy(SCIT)were included.Based on self-selected and consistently maintained injection schedules,patients were non-randomly assigned to either a morning dosing group(MD group,8:00-12:00,n=19)or an afternoon dosing group(AD group,14:00-18:00,n=20),with further subgroup stratification conducted at 2-hour intervals.Nasal and ocular symptoms were evaluated before and after treatment using the visual analog scale(VAS),and all adverse reactions were systematically recorded.Results The AD group exhibited significantly greater improvement in nasal itching compared to the MD group(median difference:-2 vs.0,U=118.5,P=0.04,effect size r=0.33).The AD group also demonstrated favorable trends toward improved sneezing,nasal congestion,rhinorrhea,and total VAS score,although these differences did not reach statistical significance.In the subgroup analysis by 2-hour intervals,the 16:00-18:00 subgroup showed greater symptom relief than the 8:00-10:00 subgroup,though the difference was not statistically significant.No significant differences were observed between the two groups in the incidence of total,local,or systemic adverse reactions(P>0.05),and no moderate or severe systemic adverse events occurred.Conclusions This preliminary retrospective analysis indicates that afternoon administration of dual-mite SCIT,particularly between 16:00 and 18:00,may enhance the improvement of nasal symptoms without elevating safety concerns.The timing of SCIT administration could therefore represent a promising avenue for treatment optimization.
